ABSTRACT
Psoriasis, a chronic inflammatory disease is associated with a long list of comorbidities. In our practice we like to draw attention in comorbidities of psoriatic arthritis and we are adapted with cardiovascular comorbidities. A great deal remains unknown about psoriasis associated comorbidities. An understanding of these comorbidity patterns can help us to ensure better care of patients with psoriasis. Objective of the study was to find out the comorbid conditions in the patients of psoriasis. This observational case control study was conducted 150 diagnosed cases of psoriasis and 150 age matched healthy control. Purposively 150 patients of psoriasis were selected from the Dermatology OPD of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2017 to December 2018 as case. After a complete physical examination, a pre-designed structured questionnaire was fulfilled with patients and controls. To detect unknown comorbidities the following tests was done in both groups and compared: Blood sugar, urine routine and microscopic examination, serum creatinine, serum AST, ALT, GGT, and ALP levels measured by an enzymatic method, X-ray chest view, USG of whole abdomen/KUB. The diagnosed comorbidity was listed and referred for treatment accordingly. Charlson-age comorbidity index chart was used to estimate risk of mortality in two groups. The mean age of incident psoriasis was 38.64 years. Diabetes mellitus (4.67%), hypertension (4%), ischemic heart disease (IHD) (3.33%) were the top three comorbidities in patients with psoriasis. among them 11(7.33%) patients of psoriasis was with single comorbidity and 5(3.33%) of them was with multiple comorbidity. In control group 3(2%) participants was detected with comorbidity and that difference was significant statistically. In current study Charlson-Age Comorbidity index (CACI) was used as a tool to estimate the risk of mortality in two groups. The mean CACI score was 2.5 and 1 in two groups respectively and the difference was significant (p<0.05). The estimated risk of death (ERRD) score was calculated form CACI chart and the score was 2.78 and 1.47 in two groups respectively. There was no significant difference in two groups (p>0.05). The rate of occurrence of comorbidity was more in psoriasis group than in control. The listed comorbidity was in mild severity range but the risk of mortality was same in psoriasis group and control.
